SN74LVC1G157DC from lingxingic, in a SOT-363. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | I1 | input | Data input from source 1; input voltage range is 0 V to 5.5 V under the recommended operating conditions. |
| 2 | GND | power_in | Ground (0 V) reference for all voltages in the datasheet. |
| 3 | I0 | input | Data input from source 0; input voltage range is 0 V to 5.5 V under the recommended operating conditions. |
| 4 | Y | output | Multiplexer output that presents the selected input (I0 or I1) in true, non-inverted form; output swings up to VCC in active mode. |
| 5 | VCC | power_in | Supply voltage, 1.65 V to 5.5 V recommended operating range. |
| 6 | S | input | Common data select input that chooses I0 (S low) or I1 (S high); input levels follow VIH/VIL for the VCC in use. |
